VALVE.

Specification of Letters Patent.

Patented Aug. 7, 1906.

A nmm m June 17,1905. seatin 265,755.

To all whom, it may concern:

Be it known that I, J AMES BOWERS, a citizen of the United States,residing at Caldwell, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in Valves and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to numerals of reference marked thereon,which form a part of this specification.

This invention relates to an improved valve that is cheaply made, and isdesigned to furnish an outlet-pipe in the valve with alternate suppliesfrom one and then another inlet on opposed sides of the outlet-pipe.

The invention is further designed to pro vide a valve of this kind thathas a common valve-closure fitting two valve-seats and when seated onone or the other of the seats leaving a passage for fluid undisturbed,except for the valve-stem.

The invention consists in the improved valve and in the arrangements andcombinations of parts of the same, all substantially as will behereinafter set forth, and finally embraced in the claim.

Referring to the accompanying drawings, in which like numerals ofreference indicate corresponding parts in each of the figures, Figure 1is a vertical sectional view of my improved valve, showing theconstruction thereof more clearly. Fig. 2 is a horizontal sectional viewtaken at line m, Fig. 1.

In said drawings, 5 indicates the body of the valve, which embodies aguideway 6 for avalve-rod 7, and in axial alinement with said rovidedwith chambers 8 and 11, partitio iled from one another by an integralportion 9, containing a passage 10, adapted to receive the valve 12,connected to the valve-rod, and permit a reciprocal movement thereof. Atthe lower end of the valve-body the same is open and provided withfemale threads 13, adapted to receive an end connection 14,correspondingly threaded and preferably provided with male threads toengage the thread of the body 5. Within said pieceor connection 14 is aguideway 15 to provide bearings for the guide extension 16 of thevalve-plunger, said guide extension consisting of cross plates or armswhich do not close the passage-way through said piece 14, but cooperatewith the valve-rod 7 to effect a positive movement of the valve-plungertoward and from the seats. The said valve-plunger is provided withfinished opposite faces 17 and 18, and the piece 14 where it closes thechamber 11 is provided with a valve-seat 19 for the said plunger. At theopposite side of the said chamber 1 1, on the partition 9, is formedanother valve-seat 20, adapted to engage the seat 17 of the valve, andthus in the reciprocal movements of the valve-rod and valve the saidvalve is brought alternately into imother means, against the pressure oftheweight, (not shown,) which is sometimes employed to hold said valvein its lower position, the passage through the guideway 15 is open topermit the inflow or outflow of fluid, and said valve thus lifted willclose immediately into engagement with theopposite seat 20, so that thesaid fluid is permitted to pass through the passage 22 only. Byreleasing the rod 7 or forcing it down against the seat 19, by weight orotherwise, the passage through the guideway 15 is closed and fluid ispermitted to flow in from the passage 21 and outthrough the passage 22.

Having thus described the invention, what I claim as new is A valve ofthe kind described comprising a casing containing two valveseats, a pipeextending from the casing between the valveseats, a pipe abovethe uppervalve-seat, a

valve-stem reciprocating in the casing, the

IOC

casing having an inlet portion in line with the valve-stem, a guide onthe bottom of the stem to guide the stem when the stem is raised, and avalve on the stem having a face 5 both sides, and constructed to moveout of Witnesses:

the path of liquid when either of the valve- CHARLES H. PELL, seats isclosed. RUssELL M. EVERETT.

have hereunto set my hand this 10th day of June, 1905.
